Manual Load Heat Pipe Spot Welding Machine

Feihong offers the Manual Load Heat Pipe Spot Welding Machine, a specialized resistance welding system designed for sealing the bottom end of single‑hair heat pipes with manual workpiece loading. As a trusted China supplier with over 30 years of manufacturing experience, Feihong combines capacitor discharge spot welding technology with pneumatic manipulator control and vibratory feeder assistance, while keeping the loading step operator‑controlled. The machine operates at 5KVA power, 380V voltage, and 0.6Mpa air source. This manual‑load approach gives operators direct control over workpiece placement, enabling quick adaptation to different heat pipe sizes and allowing visual inspection of each component before welding.

Manual Loading Design

Unlike fully automated systems, this equipment retains manual loading as a deliberate design choice. The operator places each heat pipe into the positioning groove, where vacuum attachment secures it in place before the welding sequence begins. This approach offers several practical advantages for manufacturers who value flexibility and operator oversight in their production process.

Key benefits of manual loading include:

1. Direct quality control – Operators can visually inspect each workpiece before welding, catching surface defects or dimensional issues early.

2. Quick changeover – Switching between different heat pipe sizes requires only changing the positioning groove, with no complex feeder recalibration.

3. Lower capital investment – The Manual Load Heat Pipe Spot Welding Machine costs less than fully automated systems while delivering the same welding quality.

4. Operator engagement – Skilled operators can adjust loading technique to accommodate slight variations in workpiece geometry.

This design makes the machine particularly suitable for job shops, R&D facilities, and production lines with frequent product changeovers.

Vibratory Feeder Assistance

While loading is manual, the electromagnetic vibrating disc feeder assists by orienting and presenting components to the operator in a consistent, accessible position. The feeder reduces the time operators spend searching for and orienting parts, allowing them to focus on precise placement and visual inspection. The vibratory disc can be adjusted for feed rate to match operator pace.

Feeder support functions include:

● Consistent part presentation – Components are delivered in the correct orientation for easy pickup.

● Adjustable feed rate – The operator can control the speed of part delivery.

● Reduced handling errors – Fewer misoriented parts reach the welding station.

● Easy access – The feeder positions parts within comfortable reach of the operator.

This combination of manual loading with feeder assistance creates a productive workflow that leverages both human judgment and machine efficiency.

Operational Workflow

The typical operating sequence for this welding equipment follows a clear, operator‑driven workflow that maximizes productivity while maintaining quality control.

Step‑by‑step operation includes:

1. Part presentation – The vibratory feeder delivers oriented heat pipes to the pickup position.

2. Manual loading – The operator picks up the heat pipe, inspects it, and places it into the positioning groove.

3. Vacuum attachment – The vacuum system secures the workpiece in the correct position.

4. Automatic welding – The swing cylinder moves the part to the welding station, where the capacitor discharge system performs the spot weld.

5. Unload – The operator removes the welded part and places it in the finished goods container.

This workflow allows one operator to achieve consistent welding results while maintaining visual oversight of each unit produced.
